WrNDING ENGINE. f

Ap`p1ieatien's1ea December 1e, `1925. #serial No. 75,712.-

VThis invention relates to'winding'engines,

pableA of ready transportirrespective of the character of the ,ground surfaceoverwhich they are to -be used.l lWhere loggingf'or stump-pulling operations, for.V example, :are carried on 1n uneven and hilly countries,-

sections are frequently encounteredjwhich are toolrough tobe equipment. 4 y and'readily trans ortableand is sufficiently profitable for standard flexible .or rockabe in itsframingfto allow;

of readyuse over rough groundfis accord ingly highly` desirable. To the accomplishment'of the foregoingK and related ,obiects therefor, the invention, then, :consists of the means hereinafter fullypdescribed and particularly pointed out in theclaims. e

The yannexed drawings :and the following description set-forth in detail "certain Vmecha.-

jnism embodying the inventiomsuch disclosed means constituting,fhowever, but Vone ofi va- 'riousfmechanical forms 'in which the printhe numeral lqdesignates a sled-like'skid which may be made in one' piece, or-more advantageously may. `be -builtup? ofsteels1de members united by cross girts andhawnga plate-like bottom extending .up well at each n end, thus providing protectionv of 'the' worlr Y ing partsv from dirt vandobstructions. Ex-

tending from the skid, preferably vsubstantially horizontally at one end, is an Outrigger'v v Y n may-.Abe attached-to theslnd; at theop'enings v apparatus for windingorpulling'use .in con f.' 1

2 which preferablyy is construetedz of me'mbers united 2in' sx1-braced Vpor* vV :shapeV and .adapted tol carry fat the. extremity', a cabledirecting-guide'y 3 lof-any ysuitable form.

Mounted within the' skid: is a -winding-drum 4, this being arrangedftofbe driven'froin a shaft .-5, through gears 6 and '77,- andA having. a

suitable clutch controlled.` by-a-lever S-.and

ybrake band controlled by a lever 9.Y .Ther j shaft 5-is driven through .the intermediaryof the gear 10 by gear A11 on the main power f' shaft 12. This power shaft is larranged-in Ya portablepower unit V'comprising a motor 13,l fon a framelfl which issupported frornthe' ground. at one end `bywheelspl equipped for steering .and controlledk by av steerin columnimd .wheelof anyf'usual or desire An.,fequ1pmentl which is `light i character. Advantageously such` vportable power unit may be `adapted froma motor driven' vehicle, preferably of tractor type such as may be had commercially, and toflexf lbly v.connect such rpower unit with the skid,

I mount the `power `shaft `12 in bearingsl Y i in. said skid, no other connection being, em- Y ployed." Where. a commercial motor driveny vehicle isused, the rear wheels. thereof arel removed `and'the'rear axle constitutes the drivefshaft 12 as shown. 10'thus serves to itransmitfpower from the shaft 12 tothedrum 4, and the rate of transmission can be variedasdesi'red bymeans ofv the .gea-r set embodied inthe `power unit.

PATENT oF Gearing .11, and Y. l

Mounted-above thel bearings ofthe drum 4,

there `may be additionally provided` an Vauxiliary frame' 16 in' whichV there is asecondfy -drum- 17V which-1 maybe driven .fromY the source of power by suit-able intermediary usual -or"conventionalgform. Ay seat 22l is provided sofas to kbe mounted to-'face either toward .the steering Vcolumn when the'. tractor in particulanis being used or tojbe faced In' use, the assembly may bei transported by 1 theI power' unit l,equippedl with its usual vrear wheelsfor traction and the skid may be f' hitchedV onto f the draw bar by theputrigger 2 and may be thus drawnv along zsled-wise kor connections but `which referably,willcom-v i prise a chain belt 18.y -x his second 4drum is controlled l.by 'a' thrust clutch having a handle 519. YV:[f:the-auxiliary'frame and seeond drumfare not desired, the main drum.Y bearings are simply capped over with bearingblocksfof t sof etV1

'where desired ashaft and bogie'truck wheels f 20 provided for such purpose. To setup lthe nection with logs ror'the liketherear wheels Aof they power unit are removed and the axle :isset'intothe bearings provided therefor inx the skid and. gear wheels 11 are. arranged to i mesh withrthe gears 10 on theshaft.- ,Thel

power unit .is thus seen to have no other Econnection withthe skid than the *axlev or 'shaft' kmounting v12,-a'nd by Virtue thereof, the ydevice is so flexibleyor rockable` injits by means Yof .the windup cable, extending from the drum.y through the'directing-g1 lide 3 to:` some fixed obj eetl asAv a tree. '.or ,they like.

11ov 'i In this manner, the entire assembly may be drawn from one set-up location to another, the steering wheels 15 being used to give the necessary direction to the device as it' is so drawn along. Having reached the location desired for further operation,IY the winding cable is run out to the point of action and the device is held in stable position by a cable or the like 21, which is passed about a tree or otheranchorage point and is attached at each of its ends to the connections 21'EL therefor provided on the forward end of the skid, These anchor connections', it will be noted, lie in a plane somewhat higher than that in which lies the axis of drum 4; consequently the resultant of the forces to which the skid is subjected is always downwardly when the cable or'drum' is beingwound in, i. e. is under tensioni. In

other words, the stability ofthe machine doesnot depend on the tractor at all,- `but upon the anchor connections andvstress on the pulling line does not tend to raise .the skid. Having completed operations at such set-up location, the entire assemblage may again be moved by passing the wind up cable through the direction-guide 3` to a fixed point, the device thus being drawn along as desired.

It will thus be seen that as a whole `the assemblage provides a construction which may beused in vany desired setposition for drawing logs or other pulling o ration, and vwhich is readily capable of being moved from such `position when desired either by being drawnA along on thel sled-like skid by the wind up cable,\or for longer moves the traction wheels may be applied tothe power unit and the skid may be attached `to the draw bar and be'towed along either on the sled-like base or on truck wheels as already indicated.

Other modes of applying the principle vof my invention may be employed instead of the one explained, change being made as'regards the mechanism herein disclosed, proi Y vided the 'means stated by anyof the following claims or the equivalent of such stated Ameans be employed.4 i

I therefore particularly point out and distinctly claim as my invention Y y 1.*In apparatus of the character described, the combination of a winding drum, means for supporting said drum and for 'supporting the traction end of 'a motor driven vehicle, said means comprising a skid non-rigidly and rockably connected tosuch vehicle by bearings adapted to receivek the rear axle of such ve icle, means for communicating power from such axle to the said drum, and an Outrigger and cable-guide projecting from the skid at one end.
